SAND-REEL FOR OIL-WELL RIGS.

To all whom it may concern:

Be it known that I ROYAL H. Msornn, a citizen. of the United States,residing at R. F. l). at, Box 123. Fullerton, county of Los Angeles,State of California, have invented a new and useful Sand-Reel forOil-lVell Rigs, of which the followingis a specification.

My object is to improve the mechanism for operating a sand reel bycontact with the band wheel and my invention consists of the novelfeatures herein shown described and claimed.

In the drawings: Figure 1 is a fragmen-- tary plan of the floor of astandard rig foi an oil well and showing my improved sand reelconstruction. Fig. 2 is a sectional elevation on the line 2-201? Fig. 1and looking in the direction indicated by the arrow. Fig. 3 is anenlarged top plan view of the knuckle joint post and its connections asseen looking in the direction indicated by the arrow 25 in Fig. 2. Fig.4 is a side elevation of the parts shown in Fig.1 and taken looking inthe direction indicated by the arrow 4-. Fig. 5 is a cross section onthe lines 55 in Figs. 11,2 and 6. Fig. 6 is a horizontal section on theline 66 in Fig.

Referring to the drawings in; detail, the floor of the derrick 1 is ofthe ordinary construction and the timbers 2, 3. 41, and 5 aresubstantially on the level with the floor. The band wheel 6 is mountedvupon the timher 3 and the calf wheel 7 is mounted upon the edge of thefloor 1.. Timbers 8 and 9 are mounted upon and cross wise of the timbers2 and 3. The stationary sand reel post 10 extends upwardly from thetimber 9 and the knuckle joint sand reel post 11 extends upwardly fromthe timber 8, said posts 10 and 11 being intransverse alinement. Thecast iron bearing block 12 is mounted in a recess formed horizontallyfrom the inner face of the post 11 and near its upper end. A piece ofstrap iron is bent into a U- shape and the ends of the strap iron are attached against the upper and lower sides of the bearing block 1:2 so toform the clevis loop 13. One end of the said reel shaft 14 is mounted ina bearing in the upper end of the post 10 and the other end of. thissand reel shaft 1 1 is mounted in a bearing formed horizontally in thebearing block 12, and the bearing block 12 carrying the loop, 13 ismounted to slide horizontally in the recess Specification of LettersPatent.

in the post 11. The sand reel driving pulley 15 is locatedupon theshaft, 14 in position to contact with the band wheel 6. The hinge member16 is formed upon the end of a bolt 17 which is inserted through theupper end of the post 11 above the bearing block 12. The clevis 17 isinserted through the loop 13 and a lever 18 is pivotally mountedbetween'the arms of the yoke 16 and connected tothe clevis 17*,by a pin19. The rock shaft 20 is mounted transversely upon the floor 1, therebeing a crank arm 21 upon the outer end of the rock shaft and anoperating'handie 22 upon the inner end. A rod 23 con nects the upperendaot the crank arm 21 to the lower end. of the lever 18.

W'hen the/handle 22 is pulled downwardli. f

in the direction indicated by the arrow .21 in Fig. 2 the lower end ofthe lever 18 is pulled toward the operator, bearing block 12 toward theoperator and bringing the driving pulley 15 into contact with the wheel6 so that the sand reel Qaiwvill be operated, and when the lever 22moves upwardly the sand reel driving pulley 15 will be moved out ofcontact with the band wheel.

I claim;

thereby sliding the In a sand reel construction for well rigs,'

the combination with a knuckle jointpost having a horizontal recessformed in its 1n ner face and near its upper, end, of a piece ofstrap-iron bent into a U-shape and fitting in the recess, the ends ofthe'strap-iron being bent toward each other, thus forming a clevis loop;a cast iron bearing block fitting in the clcvis loop, said bearing blockhaving a central opening to receive the sand reel shaft; a hinge memberformed upon the end of a bolt, said bolt being inserted through theupper end of the knuckle joint post above the bearing block; a clevisinserted throughthe clevis loo a lever connected to the clevis and tothe inge member and extending downwardly; a rock shaft mountedtransversely upon the floor otthe derrick; a crank arm upon the outerend of the rock shaft; a rod connecting the crank arm to the lower endof the lever; and an operat-' ing handle upon the inner end of the rock
